Re: What happen whens grafting if 2 larva go into one cell
The embryos will merge and a queen with two heads and the ability to lay twice as many eggs will emerge.
Seriously my guess would be that both larva will fail due to lack of space or they will both be removed. From what I have observed bees are very quick to recognize defective but not so keen on realizing just when they have solved the problem. they sort of go into seek and destroy mode for a bit.
Significant Minority vs Insignificant Majority, 20% of causes produce 80% of the effects.
